Hubby's internet history has left me devastated

A couple of months ago, prompted by the fact that my husband is very secretive around his devices, I went through his computer and discovered he'd not only been watching porn, but was also engaging in sex chats with strangers online.

- 

Naturally, I was shocked and very upset, but haven't said anything to him yet - it's not an easy thing to bring up. It's eating away at me, though, and makes me feel like our relationship isa total sham.

I feel betrayed and like I'm not enough for him any more. On the other side of things, he's a good provider, a very good dad and he's caring and loving towards me, but I can't forget what I've seen or how it's made me feel about him and about us going forward. Honestly, I feel like I don't even know him.
